Hi, I am using Motive 2.1 to track movement of a person in a room. I have configured Motive to track the skeleton (upper body markerset) and the skeleton looks/moves fine in Motive. I need to stream this skeleton data to my linux machine (Ubuntu 16.04) to publish the skeleton data to ROS. I found that there are ROS drivers/nodes that publish data using Natnet for rigid body, but not for skeleton.
Is there a way to publish skeleton data to ROS ?

Thank you for sharing your question here.
In Motive there is an option to stream Skeletons as Rigid Bodies. Enabling this should allow the skeleton data to come through to a client that is only receiving rigid body information.

Any ROS clients online are not our own, so I cannot speak for how they might behave or treat this data. But I imagine you should have access to the skeleton tracking using this setup.

What I was missing was some documentation for PythonClient example provided with NatNet SDK 3.1. SDK user guide does not provide that info.
I strongly recommend to have some details or Readme for using PythonClient (and other direct depacketization examples).
Simple things like- use NAT_PING in self.sendCommand() to stream the data continuously.
